Sunon PMD1206PMB1-A.(2).F.GN 12VDC Fan60mmx38mm 3pin TAC Sensor Extreme Hi-speed 56.5CFM Server/Case Fan

Inexpensive - versatile and long lasting - have used these for years - 56CFM or about the same airflow as a inexpensive 120mm fan in a space half the size - these fans fan be used with most motherboards [under 1 amp] - can be speed adjusted for quiet use. For me its the longevity of these small fans - 10 years of constant use is about normal - no led lighting and after a decade they don't look too good but they keep going - if spun up they will amputate a finger tip so a guard is advisable - yes I would recommend..
